IMPROVEMENT IN HEATERS.

Specification forming part of Letters Patent No. 40,375, dated October 20, 1863.

1'0 aZZ whom it may concern:

Be it known that l, ANTON VVELLER, of Albany, in the county of Albany and State of New York, have invented a new and Improved Radiating or Air-Heating Stove; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a vertical section of my invention, taken in the line a: 00, Fig. 2; Fig. 2, a horizontal section of the same taken in the line 3 y, Fig. 1; Fig. 3, a horizontal section of the same taken in the line 2 z, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in arranging a coldair or air-heating passage with a draft-flue and fire-chamber of a stove or air-heatingfurnace in such a manner that a very efficient heat-radiating and air-heating stove are combined, and the greatest possible amount of heat obtained from a given quantity of fuel.

To enable those skilled. in the art tofully understand and construct my invention, I will proceed to describe it.

A represents the fire-chamber or fire-pot of the stove or heater, and B the ash-box, containing a drawer, O, as usual. The ash-box is within a hollow base, D, which supports the stove or heater, and within this base and encompassing the ash-box there is a chamber,

E, the bottom of which is perforated withholes a, to form a communication with the external air. 7 v

F is another chamber within the base D, the bottom of which is tight, and communicates at its back part with the lower end of the smoke-pipe G. (See Fig. l.)

The fire-chamber A is encompassed by a cylinder, H, which extends upward its whole height, and is sufficiently larger in diameter than the fire-chamber to admit of an air-passage, b, between them, the lower end of said passage communicating with the chamber E by means of holes a, and the upper end provided with corrugations or cavities 0, projecting within the fire-pot and communicating with tubes 0, the upper ends of which register with holes d in a top plate, 0, of a cylinder, I, which encompasses the cylinder H, the former being larger in diameter than the latter, to

admit of a flue, f, being between them. The upper part of this flue f communicates with the upper part of the fire-chamber between the tubes 0, and the lower end of said flue communicates with the chamber F in the base D by means of openings g.

J is a perforated cap, which is attached to the top plate, a, of the cylinder I by a hinge, h, and K is a valve or damper fitted in an opening, 2', which forms a communication between the upper part of the flue f and the smokepipe G.

The operation is as follows: When a direct draft is requiredas, for instance, in kindling a fire-the damper K is opened, and the products of combustion pass up directly into the smoke-pipe, as indicated by the black arrows, and when the fire is fully under way and the damper closed the products of combustion pass down the flue f, through the holes or openin gs g, into chamber F, and from thence into the lower end of the smoke-pipe G, as indicated by the red arrows. The cold air is admitted either from the lower part of the room in which the stove is placed or from the outer side of the building, through suitable pipes, into the chamber E through the holes a, said air passing up through the holes a into the passage 1), where it is heated, the heated air passing through the tubes 0 and. perforated cap J into the apartment, as indicated by the blue arrows. In cases where the heated air is to be conveyed to other apartments, the tubes 0 at their upper ends may communicate with a box, from which the heated air may be conveyed by means of suitable pipes. By

this arrangement it will be seen that the air in passing up the space a is subjected to heat at both sides-to wit, from the fire-chamber A and from the fluef-and is afterward conducted through contracted passages 0 0,10-

lated directly over the fire-pot, an d surrounded by the heated products of combustion, while the heat at the outer side of the flue is radiated from the outer side of the cylinder I. Thus it will be seen that no heat is lost, it being all made available by direct radiation from the cylinder I and the heating of the air which passes up through a. The stove or heater at the same time may be constructed at a moderate cost, and it possesses no parts liable to get out of repair or become deranged by use. I

Having thus described my invention,what I J and flue Gr, all constructed, arranged, and. claim as new, and desire to secure by Letters operating in the manner and for the purposes Patent, is herein shown and described.
